London has been battered by 50mph winds that have felled trees and caused travel chaos. Powerful gusts swept across the capital as the Met Office issued a yellow "be aware" weather alert for most of the country.

While BlackBerry’s launch of its new operating system, BB10, is finally killing off the keypad on its flagship phone, the Z10, we’re regressing — and finding the best five keyboard covers for our touch-screen tablets. Here are our favourites.

Brydge+

The most effective way to turn your iPad into a clamshell laptop. The aluminium keyboard also boosts the iPad speakers. £140 ($220), thebrydge.com

Logitech Ultrathin Keyboard Cover

It is actually pretty slim — measuring less than a centimetre thick. Your iPad clicks in magnetically. Comes in white, black or red. £89.95, store.apple.com/uk

Surface Type Cover

Only for the Microsoft Surface. This is better than its cousin, the flat Touch Cover, as it has depressible keys. £109.99, Microsoft.com/surface

Kensington KeyFolio Pro 2

Works as a stand and a case for your tablet and the keyboard can be removed if you wish. £65 ($99), Kensington.com

Zagg Folio

A little bulky but the leather version of this case with a prop-up stand is smart and hardy. £129.99, zagg.com
